Diagnosis can be challenging, as symptomatology can be attributed to more common abdominal pathologies. Due to the rarity of this condition, only case reports are available to inform management.Case Presentation: We present the case of a 72-year-old woman with a ruptured middle colic artery aneurysm presenting with signs and symptoms more suggestive of acute calculous cholecystitis. Her co-existing bleed was confirmed on CT angiogram. Coil embolization was initially attempted unsuccessfully. She underwent laparotomy, a middle colic artery ligation, and extended right hemicolectomy with intra-aortic balloon placement for emergency proximal vascular control. Post-operatively, she had a re-bleed that was successfully managed with covered stent placement in the proximal superior mesenteric artery after an unsuccessful re-attempt at coil embolization. Her apparent associated cholecystitis was managed with antibiotics and resolved uneventfully.Conclusion: A middle colic artery aneurysm can be challenging to diagnose and treat. Management options include endovascular techniques, open surgery, or a combination approach. Intra-aortic balloon placement for emergency vascular control is a novel approach that could avoid hemorrhage when intra-abdominal vascular access is challenging.Keywords: middle colic artery, mesenteric aneurysm, endovascular therapy, coil embolization, intra-aortic balloon placement |
